ANTONIO MEUoci, or STAPLETON, AND rroanLLo mom, or'ivnw YORK, n.

To all whoiwit may concern I Belt known that we, ANTONIO Mnuooii, of Stapleton, in the county of Richmond and State of New York, and TORIEILLO DE'UDI, of the city, county, and State of New York, have invented a new and Improved Plastic Paste, of which the followii'ig is a "full, clear, and exact description.

The object of our invention is to provide a new and improvedplastic paste to be used for ina iiuiactuli-ing various articles of art and industryefor instance, billiard -balls, figures,

statuary, vases, moldings, and ornaments of various kinds.

Our composition consists of the :tollowing ingredients: glue. or gelatine; gunii-arabie or some analogous gum; vegetable fiber, ivory, bone, horn, or an analogous substance; cornstarch, or Indian meal, or buckwlileat-flour; gunrresin, gum-n'iastic, or gum-sandarac, or an it gum; crude petroleum, or Vaseline,

.e, or dammarvarnish, or spirits of or par 1 turpentine, or ijnuriatic acid, orstearic acid;

trate oi'potassium, (SHlhPGtBlQ oxide of zinc 'terra-alliia.

In mak the paste we proceed as follows: latine and the gum-arabie are ssolved in rater, in the proportion of about three to four partsof glueor gelatine and one part of guni-arabic, to about the consistency of molasses. thoroughly dissolved, vegetable fibers are added, which have been previously treated as described in the Patent No. 47,068, issued to Antonio Meucci on the 28th day of March,

1865-that is, the vegetable fiber or analogous substances are treated with gases gei'ierated by tl'ieactioiii of nitro-muriatic acid upon carbonate of lime, and then washed and treated with. caustic alkali, or alkali and oil, whereby the .mineral, gummy, and resinous substances are removed from the fiber or cellular matter. Then from one to two parts of corn-starch, Indian meal, or buckwheat-flour, or another equivalent substance are added and the several ingredients steadily stirred, so that they will be thoroughly mixed. After they are properly mixed, one or two parts of varnish or cookedoll made up with gum-resin or gum- -mastic and stearic acid and. dammar varnish are added. In place'of the dainmar varnish, crude petroleum, Vaseline, parafline, or spir- After the glue or gelatine hasbeen PLASTIC PASTE.

is subjected to a mild heat produced by steam.

in order that the mass will bind well, a small quantity oi. n'iuriatic acid diluted with water is added from time to time. Then small quantities of oxide of zinc, or oxide of zinc and terra-alba, are added until the desired consistency is reacl'1ed"'that, is, until the mass has sufficient body for molding. The mass is then placed into molds and subjected to pressure and to the action of heat until the objects become dry. The molds can be made of metal, terra-cotta, o any other suitable material.

In place of gelatine, ivory or bone powder may be used, the gelatine required being de rived from the ivory, horn, or bone powder. We can produce the mass in two diii'erent ways, the product or result always being the same.

\Ve will now give the two mixtures forproducing the paste. One mixture consists of the following ingredients combined in the follo ing proportions: gelatine or glue, two to four parts; muriatic acid, (diluted,) one totwo parts; oxide ofzinc, six to eight parts; terra alba, two to four parts; starch or analogousv material, one to twoparts; fiber treated a. above mentioned, Ol'lG-fOllItll to onehalf part; varnish or cooked oil, one to two parts. The other composition, which produces exactly the same result, and really oonsis of the same ingredients mixed in slightly-difl'crent proporti ons, consists of powdered bone, ivory, or horn,

In the preparation. of more delicate and ex! pensive articles, the corn-starch, Indian meal, or buckwheat flour, orgelatine is replaced by powdered bone, horn, or ivory,,wl1ich must be previously soaked in Water mixed With muriatic acid and saltp eter, (nitrate of potassium, and then boiled until they become soft and pasty and easily triturated in a mill.

The above-described paste can be manufactured very easily, is cheap, not explosive, and forms a hard and elastic mass.

Having thus described our invention, We claim as new and desire to secure by Letters Patent- 1-. The herein-described composition of matter, consisting of gelatine or a substance containing gelatine, fiber deprived of its mineral, gummy, and resinous substances, varnish, ox-

'ide of zinc, terra-alba, and an acid mixed in the proportions given, as set forth.-

2. The herein-described composition of matter, consisting of gelatine or a substance containing gelatine, fiber deprived of itsmineral, 1 i gummy, and resinous substances, an acid, starch, or analogous substances, varnish, oxide of zinc, and terra-alba, mixed in the pro-' portions given, as set forth. v
